How do nematocysts get venom?
There is a coiled thread extending into the cavity of this capsule. When stimulated, the nematocyst lid opens and the thread is blown out with explosive force, penetrating the prey. There are about 30 different types of nematocysts, and some of them have hollow threads that allow the contents of the capsule to exit through them and enter the prey. They can also contain simple threads or glues to entangle and immobilize prey. The capsular contents can, however, be venoms of significant toxicity (Hesslinger and Lenhoff 1988, Kozloff 1990, Ruppert and Barnes 1994, Russell and Watson 1995, Thorington and Hesslinger 1996). Additionally, they are often specific to the type of prey, so that if the anemone eats fish, its nematocyst venom is specific to vertebrates and won’t necessarily affect shrimps or squids. Such vertebrate-specific venom will, however, affect aquarists.
